            'downloading', 'finished', 'seeding', 'allocating']
    print '%.2f%% complete (down: %.1f kb/s up: %.1f kB/s peers: %d) %s' % \
            (s.progress * 100, s.download_rate / 1000, s.upload_rate / 1000, \

Would it be possible to replace the magnet link with a .torrent? How could I do that?

ses = lt.session({'listen_interfaces': '0.0.0.0:6881'})
    # look here, link is one of .torrent file's path
    info = lt.torrent_info(link)
    h = ses.add_torrent({'ti':info, 'save_path':'/Downloads'})
    s = h.status()
    print('starting', s.name)

    while not s.is_seeding:
        s = h.status()

        print('\r%.2f%% complete (down: %.1f kB/s up: %.1f kB/s peers: %d) %s' % (
            s.progress * 100, s.download_rate / 1000, s.upload_rate / 1000,
            s.num_peers, s.state), end=' ')

        alerts = ses.pop_alerts()
        for a in alerts:
            if a.category() & lt.alert.category_t.error_notification:
                print(a)
        sys.stdout.flush()
        time.sleep(1)
    print(h.status().name, 'complete')

Is it possible to pass a proxy configuration for the download?

can I view the files in the big torrent, and select specific files to download, instead of downloading everything?
